3 Claims. (Cl. 229-51) This invention relates to an improvement in icecream carton and deals particularly with a carton which may be filledfrom the end in the conventional manner and which may be readily openedup in the manner of a trunk style carton for the dispensing of thecontents.

For many years ice cream has been usually sold in generally rectangularend opening packages which are of greater height than width orthickness. During recent years when the use of home freezers has becomecustomary, the sale of half gallon packages of ice cream has increased.When the half gallons of ice cream are sold in the conventional types ofcartons, it is difficult to remove all of the ice cream with a spoon orsimilar utensil due to the depth of the carton. It is an object of thepresent invention to provide a carton adapted to obtain a half gallon ofthe product, which can be filled from the end in a conventional manner,and which may be opened up in a manner to form a closure in one of thelarger panels so that the contents may be more readily dispensed.

A further feature of the present invention resides in the provision of arectangular carton which requires little more paperboard than theconventional rectangular carton, and which may be closed in a manner toform a readily reclosable carton structure.

These and other objects and novel features of the present invention willhe more clearly and fully set forth in the following specification andclaims.

In the drawings forming a part of the specification;

FIGURE 1 is a perspective view of a closed carton which has been filledwith the product.

FIGURE 2 illustrates the carton of FIGURE 1 in open position.

FIGURE 3 is a diagrammatic view of the flat blank after themanufacturers joint has been formed.

FIGURE 4 is a diagrammatic view of the blank from which the carton isformed.

FIGURE 5 is a perspective view of a closed carton of modified form.

FIGURE 6 is a perspective view of the carton after it has been opened.

FIGURE 7 is a diagrammatic view of the blank from which the carton isformed.

The carton A illustrated in FIGURES 14 of the drawings includes a frontwall panel 10, a bottom panel 11, a rear wall panel 12, and a top panel13 which are foldably connected along parallel fold lines 14, 15 and 16.A front cover flap 17 is hingedly connected to the front wall panel 13along a fold line 19. Cover side flaps 26 are foldably connected alongopposite sides of the top panel 13 along parallel fold lines 21 whichintersect the previously described fold lines at right angles. Cornerflaps 22 are hingedly connected to the ends of the cover front flap 17along extensions of the fold lines 21.

End walls 23 or end closure flaps are hingedly connected to the bottompanel 11 along parallel fold lines which are generally extensions of thefold lines 21 but which may be inwardly offset slightly to simplify theformation of the carton end walls. The flaps 23 are the full area of theends of the carton so as to form full closure panels. Closure flaps 24are hingedly connected to the ends of the rear wall panel 21 and similarflaps 25 are foldably connected to the ends of the front wall 10. Theflaps 24 are of proper length to overlap one another.

In preferred form a generally rectangular area 26 of heat actuatedadhesive are printed on the front wall flaps 25 in the areas thereofwhich overlap the flaps 24 when the carton is closed. Areas 27 of heatactivated adhesive are also printed upon the inner surfaces of the coverside flaps 2% in the areas thereof which overlap the corner flaps 22when the carton is closed. By applying heat to the ends of the carton,the corner flaps 22 may be sealed to the cover side fiaps 20, and thefront and rear wall end closure flaps 24 and 25 may be sealed inoverlapping relation outwardly of the full size panels 23.

In preferred form, the cover front flap 17 is provided with a series ofparallel embossed crease lines 2% which have a tendency to space thelower edge of the flap 17 from the front panel 10 when the flap 17 isglued to the front panel 10. Normally, spots of adhesive 30 locatedbetween the score lines 29 and the fold line 19 are used to attach thefront cover flap 17 to the front wall. A zigzag cut score line 31extends across the front panel 11 in spaced relation to the end of theblank, and the spots of adhesive are located between the zig-zag cutscore line 31 and the upper edge of the front Wall 1.0 when the cartonis glued in tubular form. This arrangement permits the outer surface ofthe front panel to peel off readily when the carton is opened if theadhesive is bonded sufficiently not to come loose when the carton isopened.

When the carton is glued in tubular form as shown in FIGURE 3, thecarton may be opened up or squared up in the usual manner, and one endof the carton may then be closed. This is accomplished by first foldingthe full size flaps 2.3 into right angular relation to the bottom panel11, forming the end closing flaps 2-4 to overlie the bottom closureflaps 23, and then folding the rear wall closing flaps 25 intooverlapping relation with the ends of the fiaps .24. As the flaps 25 arefolded downwardly, the overlying corner flaps 22 are also foldeddownwardly to overlie the flaps 25. The flaps 26 are then foldeddownwarclly to overlie the fiaps 22 and portions of the flaps 24 and 25.Heat is applied to connect the flaps 24 and 25 in overlapping relation,and also to connect the cover front flap 17 to the cover side flaps 20by attaching the corner flaps 22 and the side cover flaps 29.

When the carton has been filled and closed, it may be opened by graspingthe edge of the cover front flap 1'7 or inserting a knife or similarinstrument between the front panel 10 and the flap 17 to sever the areasof adhesive 31 The cover panel, together with its front and side flapsmay then be opened up in the manner illustrated in FIGURE 2 of thedrawings for the easy dispensing of the carton contents.

The carton B is in many ways preferable to the carton A althoughincludes slightly more paperboard. The carton B includes a front panel4i), a bottom panel 41, a rear wall 42, and a top panel 43 which areconnected together along parallel lines of fold 44, 45, and 46. A coverfront flap indicated in general by the numeral 47 is connected to theforward edge of the top panel 43 along a fold line 49. The cover frontflap 47 is divided into three sections by a pair of parallel weakenedlines of separation 5t and 51 which define a removable tear stripportion 52 therebetween. This arrangement provides an upper portion 53which forms a part of the carton lid when the tear strip 52 is removed,and provides a marginal anchoring portion 54 which is adhered to thefront panel 41 when the carton is glued in tubular form.

The cover 43 is also provided with a pair of cover side flaps 55 whichare of approximately the same width as the upper portion 53 of the coverfront flap 47. Corner flaps 56 are hinged to the ends of the upper flatportion 53 and are designed to seal in face contact to the top sideflaps 55 connected to the cover panel 43 along parallel fold lines 57.For this purpose, areas 59 of E-activated 3 adhesive are usually printedon the surfaces of the cover side flaps 55 on the area thereof whichoverlaps the corner flaps 56. The bottom panel 41 is hingedly connectedto end panels or end wall flaps 60 which are substantially of the crosssectional area of the ends of the carton so as to form a full closure.End closure flaps 61 are hingedly connected to the ends of the rear wall42 While end flaps 62 are hingedly connected to the ends of the frontwall 40. The flaps 60, 61, and 62 are connected to their various panelsalong fold lines which are generally aligned with the fold lines 57which might be slightly offset therefrom to compensate for the thicknessof the flaps forming the enclosures. The flaps 61 and 62 are of properlength to overlap, and the flaps 62 are provided with areas 64 ofadhesive which is activated by heat.

The carton B is formed into tubular relation by adhering the surface ofthe anchoring portion 54 of the cover front flap structure 47 to thefront carton wall 40. In use, one carton end is normally sealed closed,the carton filled, and the other end closed. In doing this, the endflaps 60 of the bottom panel are folded upwardly into right angularrelation to the panel 41, and end flaps 61 and 62 are then folded intooverlapping relation. During this operation, the corner flaps 56 arefolded to overlie the end flaps 62, and the cover side flaps 55 arefolded to overlie the corner flaps 56. Heat, high frequency current, orthe like is applied to activate the adhesive areas 59 and 64 and tocause the ends to seal.

When the cartonis to be opened, one end of the tear strip 52 is grasped,and this tear strip is removed leaving the anchoring area 54 adhered tothe front panel of the carton. The carton thus formed has a hinged lidwhich may be readily seen in FIGURE 6 of the drawings, and the contentsof the carton may be Wholly or partially removed. The arrangement issuch that the lid may be readily reclosed to form a good closure.

In accordance with the patent statutes, the principles of constructionand operation of this improvement in ice cream cartons have beendescribed, and while an endeavor has been made to set forth the bestembodiment thereof, it should be understood that changes may be madeWithin the scope of the following claims without departing from thespirit of the invention.
